FLOAT-VALVE.

Specification of Letters Patent.

' Patented Merch 3o, 1909.

Application led June'l, 1907. Serial No. 377,682.

.l 'To all whom it may concern:

Be it known that I, GOTTLOB E. LOEBLE, a citizeny of the United States,residin in the city of New York, borough of Brooklyn, in the county ofKings and State of New York, have invented a .certain new and usefulImrovement in Float-Valves, of which the folowing is a specification.

, The invention relates toself-closing valves ofthe ball-cock class, andits object is to provide a simple, inexpensive valve` with aclosing-float, which shall be positive in operation and not liable toderangement.

. the tank.

,through the valvecasing and iioat, on a f The invention consists incertain novel features and details of construction by which the aboveobjects'are attained, to be hereinafter described.'

The accompanying drawings form a .part of this'specification and showthe invention las applied to flushing-tanks.

Figure 1 is a vertical section through a tank,A showing the valve-casingand its conl nected parts in elevation. In this form the water supplgfenters through the bottom of `ig. 2 is a corresponding section largerscale. Fig. 3 is a lan view of the float.- Fig. 4 1s a section t rough aportion f of a fiushing-tank, on the same scale as Fig.

' any ordinary 1, showing the invention adapted forservice with ay suppl-pipe entering the side of the tank. The oat is shown in section, withthe valve-casing in elevat on. ,-Fig.''5 is a vertical section, partlyin e evation, showing on a larger scale the valve in the preceding'figure.

Similar letters'- of reference indicate like parts in all the figures.-

Referring to Figs. 1, 2 and 3, A is the tank adapted to receive waterthrough a supplypi e Brat the bottom and deliver it ,through aushi'ng-valve C and flushing-pi e C, operated by a lever D fulcrurned ona ar extending across the tank, all of which may be of or approvedconstruction. The valve controlling the inlet comprises a casing Ewithin the tank, screwed upon the end of the lpipe B and` having ahorizontal diaphragm J on the lower face of which is a valve-seat Freceiving a conical valve G on a verticallvmovable valve-stem H guidedin s iders above and below the diaphragm El. 'lille upper or deliveryend of the casing E is open to allow water to flow freely' therethroughwhen the valve is depressed, and is `flushing-valve reseated by gravity;

covered by a dome-shaped hood or dellector I attached by arms I1 to ascrew-threaded ring I2 screwed on the upper end of the casing, servingto interce t the vertical jet therefrom and deflect t e water downwardtoward the bottom of the tank. The valvestem lII extends loosel throu hthe deflector I and is continue vertieIly upward,

terminatin in a head or disk K immediately- A below the ong arm of thelever D and arranged to be struck and forced downward thereby to o enthe valve by the act of raising the fius ing valve C. Onthe valvestem,above the deiector, inclosing the latter and a portion of the casing E,is secured the float L which is in the form of an inverted cu closed atthe top, through which' the valve-stem extends axially, and open at thebottom. It is so located relatively to'the valve and tank as to yriseand lift the valve,

` and shut off the supply when the Water level has risen to the helghtin the tank to which4 the float has been set.

Assuming the tank to' contain a supply of water, a downward ull on thelong arm of the lever D lifts the ushing-valve C and'per-` mits thewater to escape through the `Ilush1n9; pipe Cl until the lever isreleased and the downward movement of the lever-arm depresses the valveG in opposition to the pressure in the pipe B and permits watertherefrom to flow past the valve into the no w empty tank. The valve isheld in the open condition by its gravity and that of the float andvalve-stern, and the flow continues until the water level risessufficiently to im rison a volume of air in the open-mouthed) float andthe displacement thus produced raises the float and lifts thevalve toits seat, the closing movement being aided by the current of waterflowing )past 'the valve in the direction to close it. I closed it isheld to its seat by the water pressure until the valve-stem is againforced downward The action is similar in the arrangement shown in Figs.4 and 5. In these figures the supply-pipe B1 is at the side of the tankA1 and joins a valve-casing E having a downwardly projecting portion E3having a diaphragm E4. 'The valve-seat'F1 is on the upper face of thediaphragm. In this form the pressure side, and the valve Gr1 o ensupwardly. Guides J receive the va ve-stem the Samet hen the valve isthus as at h to receive the end M1 of a lever M fulcrumed at m to adownwardly extendinglug E5 on the valve-casing E3. On the lever M is ailoat L1 similar to the float above described. The action is the sanfeas in the first form excepting the valve is lifted fro'm its seat by thegravity of the ioat L1 acting through the lever M instead of being actedupon by the ushing lever. Water flowing past the valve Grx graduallyfills the tank until the loat L1 rises and draws the valve downward, inthe direction of the flow, to its seat on which it is held as before bythe service. ressure until overcome by the gravity of t e float LL asthe latter descends.

In both forms the valve is seated in the direction of the current, andis held in the closed condition by the water pressure, thus avoidingdanger of lleak and obviating the' use of stufling-boxes or likedevices, and the cup-shaped iloat reduces the expense and f annoyanceattending the employment of the usual -water-tight ball.

Especial im ortance is attachedV to the form shown in lgs.y 1, 2, and 3on account of its simplicity. The direct attachment ofthe floatconcentrically to the valvestem reduces the number of parts, and lessensthe vexpense of manufacture; this construction also effects aconsiderable `saving in space, thus permitting the valve to be installedand operated successfully in narrow quarters.

I claim l y 1. Ina float valve device, a tank, a casing therein mountedupon the supply pipe and having therein a horizontal diaphragm with avalve seat on its underside, a 'vertically v movable valve stem, guidestherefor above and below the diaphragm, a conical valve on said stem,the up erxend of said casing being open, a dome-shaped hood supportedfrom the upper end of said casing and having a central opening throughwhich the valve stem passes, and a iioat sup orted on said stem,concentric with said Eood, with its lower end extended below the loweredge of the hood and forming an airv chamber around a valve seat on itsunder side, a vertically movable valvefstem, guides therefor above`and'below the diaphragm, a conical valve on l'said'steirL the upper endof said casing being open, a dome-shaped hood supported from the upperend ol" said casing and having a central opening through whichthevalvestem passes, and a ioat sup orted on said stem, concentric with saidood, with its lower end extended below the lower edge of the hood andforming an air chamber around the hood and between the same and the wallof the 'float both above vand below said hood, said casing being formedof detachable parts and the hood being vertically adjustable on theuppermost of said parts.

3. In a float valve' device, a tank, a casing therein mounted upon thesupply pipe and having therein a horizontal diaphragm with on said stem,the upper end of said casing.

being open, a dome-shaped hood supported from the upper end of saidcasing and having v a central opening through which the valve stempasses, and a float sup orted on said stern,l concentric with saidlifood, with its lower end extended below the lower edge of the hood andforming an air chamber around the hood and between the same and the wallof the float both above and below said hood, said hood being detachablysecured upon the upper end of the casing and saidffloat being directlylattached to the valve stem and concentric therewith.

In testimony that I claim the invention above set forth I affix mysignature, in presence of two witnesses.
